SPEED-REGULATOR FOR KEROSENE-OlL ENGINES.

SPECIFICATION forming part of Letters Patent No. 741,791, dated October 20, 1903.

Applicationfiled July 5, 1902. Serial No. 114,848. (No model.)

To all whom, it may concern:

Be it known that LFEoDoR G. Hrnsoma citizen of the United States, residing in the city, county, and State of New York, have inventedcertain new and useful Improvements in Speed-Regulators for Kerosene-Oil Engines, of which the following is a specification sufficient to enable others skilled in the art to which the invention appertains to make and use the same.

My improvements relate to speed regulators for kerosene-oil engines, and are designed to regulate the resistance to be overcome by the govern or and automatically regulate the oil-feed, and incidentally to attain greater delicacy and quickness of adjustment, substantially as hereinafter described and claimed specifically.

In the accompanying drawings, Figure 1 is an end elevation, partly in section, showing the application of my improved apparatus ap? plied to a kerosene-oil engine. Fig. 2 is a sectional elevation, partly broken away, of the resistance-regulator. Fig. 3 is a view taken at right angles to Fig.1. Fig.4is a plan.

A represents the casing of a kerosene-oil engine of ordinary construction," of which E is the power-shaft and O the cam-shaft, carrying the usual cams for operating the engine-valves. On this cam-shaft C is also situated a cam c for operating the oil-pump P through the medium of the plunger D, preferably carrying an antifriction-roller d,which is held in contact with the earn 0 by the spring cl within the guiding-tube E, through the lower portion of which the end (1 protrudes.

G is a governor of a centrifugal class actuated by the cam-shaft through the medium of bevel-gears g g. The governor-slide 9 acts upon the bifurcated arm f of the lever F, the other end f of which is pivotally connected with the connecting-rod H, by which the lever F is coupled to the short arm of the rock-lever I, the opposite arm of said rocklever carrying a wedge W, pivotally connected thereto. The wedge W is interposed between the inner end (1 ofthe plunger D and the upper endp of the pump-rod. The throw of the cam a is considerably less than the distance between the opposed ends d and 19, so that were it not for the interposition of the wedge W the earn 0 could not operate the pump. The wedge W is held against the upper end of the pump-rod by a spring to or equivalent means. It is obvious that if the wedge is advanced or retracted by the action of the governor G the stroke of the pump-rod will be correspondingly varied to regulate the supply of oil forced by the pump P into the pipe 10, which leads to the ignition-chamber of the engine.

In order to vary the resistance to be overcome by the governor, and thereby vary the speed of the engine through the oil-feed, I pivotally connect the rock-lever I with a plun- 6 5 ger-rod It, the upper end of which travels in a sleeve or cylinder L, said cylinder L being pivotally connected to a hand-lever M, having a pawl m, which engages with a segmental rack N. lnterposed between the upper end of the cylinder L and the head k. of the plunger-rod is a compressible spring S.

When the parts'are in the position illustrated in Fig. 1, the spring S is compressed and exerts its full resistance, through the medium of the rock-lever I, connecting-rod H, and bifurcated lever F, against the centrifugal action of the governor G. As the handlever H is thrown upward to its fullest extent the spring S expands until the head 7r. of the plunger 70 comes in contact with the end plug 1 of the cylinder L, thereby causing the plunger 7.: to raise the long arm of the rock-levers I and F, and thereby so far retract the wedge W that the inner end d of the plungerl) will fail to reach said wedge, and hence the pump P will not be operated. It is obvious that by regulating the position of the wedge W by means of the l1ELH(ll6V6tI"I between these two extremes the stroke of the pump-rod 19 may go be regulated with accuracy and delicacy, the degree of compression of the spring S, and consequently of the resistance afiorded to the centrifugal action of the governor, admitting of the regulation of the speed of the motor by the control of the feed of oil.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination of a keroseneoil engine,

a pump for supplying oil to said engine, a

feed-cam upon the cam-shaft, a plunger actuated by said feed-cam, the pump-rod in line with but separate from said plunger with the distance between the opposing ends of the plunger and pump-rod greater than the throw of the cam, a wedge interposed between the opposite ends of said plunger and the pumprod, said Wedge being controlled by means of a centrifugal governor actuated by the camshaft together with said centrifugal governor and connections, a pivotally-mounted handlever, a cylinder connected therewith and with the Wedge, and a compressible spring in said cylinder acting upon the connection between the same and the wedge.

2. The combination of a kerosene-oil engine, a pump for supplying oil to said engine, a feed-cam upon the cam-shaft, a plunger actuated by said feed-cam, the pump-rod in line with but separate from said plunger with the distance between the opposing ends of the plunger and pump-rod greater than the throw 20 of the cam, a wedge interposed between the acting upon the connection between the sameand the wedge.
